"There are several issues that must be resolved before 5G can become a reality," said rotating CEO, Eric Xu.

"These include the availability of spectrum and technological challenges, such as how to engineer network architectures capable of handling increasingly higher data volumes and transmission speeds necessary to accommodate more users on the network."

Xu added that while Huawei had achieved breakthroughs in 5G research, "the majority of the work remains ahead of us." ®
